2-Aminophenol → 2-(1-Methylpentylamino)phenol

Participants

Reaction Steps

The same procedure as in Example 3 was repeated except for using 145 mL (121 g; 1.2 mol) of 2-hexanone in place of 100 mL of acetone, to conduct the reaction. As a result, it was confirmed that the rate of conversion of o-aminophenol was 93%, the selectivity to the N-monoalkylated compound (molar ratio of the monoalkylated compound to a sum of the mono- and di-alkylated compounds) was 41%, and the oxygen absorption initiation time as an index of determining an oxidation-inhibiting property thereof was 320 min.
